Hungry Horse a prime location for pumped storage hydropower

One of the most efficient ways to store energy is to pump water from one reservoir to another higher reservoir. The energy used in the pumping can then be recovered at a later time by releasing the water into turbines generating electricity.

This technology, pumped storage hydropower, has been used for decades in Europe and America with efficiencies of 80%.

Why is this technology of particular interest to Montana? This state has a great potential for wind power. Already there are many wind machines at Judith Gap and another cluster near the Canadian border. A problem of wind energy is variability. Winds are never steady for long periods of time. A fluctuating source of electricity has very little market value. Solar power has the same disadvantage.
